Silicon crystal cutting auxiliary tool

Abstract

The invention discloses a silicon crystal cutting auxiliary tool. The silicon crystal cutting auxiliary tool has a bilaterally symmetric structure, wherein a straight tube, a tube hole, a plug, a circular tube and a hanging hook are arranged on one side of the tool; the straight tube is formed by sleeving an inner tube and an outer tube with hollow circular tube structures in a concentric circle form; the tube hole is formed on the inner tube; a tube seam is reverse to the direction of the tube hole and is relatively arranged on the outer tube; the tube hole can be closed or opened through a screw; the plug is connected with one end of the straight tube; the circular tube is arranged in the plug and is communicated with the inner tube; the hanging hook is fixed on the side face of the plug; a connection part of the plug and the inner tube is right-angled; and thus the bilaterally symmetric U-shaped silicon crystal cutting auxiliary tool is constructed. The flow and uniformity of mortar in the tube are adjusted and controlled in a silicon crystal cutting process by closing or opening the tube hole on the straight tube through the screw, so that the tool contributes to improving the surface quality of a silicon slice, solving the problem of influence on capability of driving mortar through a steel wire due to different mediums and fulfilling the aims of improving the quality of silicon crystal slices, reducing loss of silicon crystals and saving production cost.

Description

technical field [0001] The invention relates to the technical field of crystalline silicon block processing, and more specifically relates to an auxiliary tool for cutting silicon crystals. Background technique [0002] With the continuous development of the world economy and the increasing demand for high-efficiency energy in modernization, especially the rapid population growth and the ensuing deterioration of the living environment, all countries in the world will improve the environment as an indispensable part of sustainable economic development.
